SPECIFICATION forming part of Letters Patent 0. 781,799, dated Febzparm 7, 1906 Application filed November 25, 1904. Serial Ho. 23;;120. i

"of West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improve'mentsin- Self-Lubri- ,catingiPulleyrINheels and the Like, of which the following is a specification.

The invention relates to improvements in self lubricating pulley wheels and the like;

. and it'consists in the novel features and com 'bipations of parts hereinafter described and claimedw The object of the invention is to produce a hub' construction adapted to form a reservoir for the lubricant and which will assure the maintenance of a proper body of oil at the bearing-surface of said hub;

'- One of the essential objects of my invention is to overcome the general objection to self- 'oiling wheels-'that the centrifugal action carries' the oil to the outer portions of the'reser- 'voir and the bearing-surfaces are insufiiciently lubricated; and in carrying out my invention I provide within the chambered hub of the wheel stationary meanswhich@ part prevent the oil from being toan undue extent thrown outwardly during the rotation of the wheel- I and which feed the oil from the upper side of hub. The oil"whichpas ses1to.the shait on which the w eel isv loosely 'inounted'travels the chamber to the bearing-surfaces of the between the {lie-and thev bearing-surfaces of thehubJand returns through suitable apertnres or inlet-ports in the hub to the reser voir to be used over again in lubricating'said" su-rfaces; whereby I not only feed oil to'said surfaces, but maintain a suitablesupply of the same thcreat.

-4 The invention will be any understood mm 4 the detailed description hereinafter'presented, reference being had to the accompanying drawings, in which.

'Figure1is a central vertical longitudinal section, partly broken-away, of -a pulleywheel constructed inaceordance with and embodyin the invention, jthefsectiou being i on 4 the dotted line 1-,-1 of Eigi 2. Fig-.2 isa cenftral vertical transverse sectionof same onthe' sedottedline 2 2 ofjEig. 1',2- and -;Fig. "3 is a dethe oil andfeed the oil to the bearing-surfaces.

In the drawings, 10 designates a'pulleywheel loose upon a shaft 11, said wheel being composed of two corresponding parts 12 13, fitted and secured together by an annular tongue and groove 14 and screws or bolts 15. 'The wheel parts 12 13 have hub-sections 16 17, beyond whichwithin the'hub'portion of the wheel is formed a chamber or reservoir 18 for the oil, said chamber being of adequate capacity in accordance with the size of the wheel and one wall of which being supplied with a filling-orificci19, adapted to be closed by a plug 20.

-The hub-sections 1617 have within their outer'edges the 'annularugrooves 21, from n which return-ports 22 leadto the chamber -oireservoir 18, and the said sections16 17 are separated from each other at theirY inner edges and receive freely betweetL-thmthe eccentrically-shaped weight or pendent hddy upon theinner portions of the huh sections 16 17.: 'The body 23 extendsbelowthe' Shaft 11 tonearly the outer edge of the chamber 18,,while abo've said shaft said bodrtermi-f nates at its hubflanges 2i and is-there pro- ,V'ided with a series of vertical apertures 25, open at both ends and leading to the shaft 11;

and the central one of which, aperturee js in communication with a conduit26, whichiis in the form of. a tube havingl openings in its sides and which I preferto form oflwire coiled in the manner of a spring; The con duit 26 extends upwardly toa point in near relation to the outer edge of'the chamber 18.

. T In the employment of the invention a suitable quantity of the oil is supplied to the chamber or reservoir 18, and thereafter when 23 will remain stationary,- or substantially ,so, and-the. oil will be carried around by the walls of "the chamber 18 and centrifugal action.- The oil carried. above the shaft/11 will be partly intercepted omits-passage by the conduit 26, which standing in the ath of the oil' will .-be strucit by'the same ith the revthe wheel is set in' motion the pendent body I op 6 east Av MLABLE will fall upon the upper end of the body 23 and pass throu h the exposed apertures 25 to the shaft -11. he oil which passes through I the conduit 26 and apertures 25 will travel i along the shaft 11- and inner surfaces of the hub-secti0ns 16 17 and finally reach'the{ grooves 21, whence, dueto centrifugal action, 'it will pass through the ports 22- and return to the reservoir 18. Thus there will during the use'of the wheel be a constant circulation of the oil from the reservoir through the apertures 25 and conduit 26 to the shaft 11, thence along said shaft to the annular grooves 21, and'thence through theretiirn-ports'22' to said reservoir.

The pendent weighted. body 23 maintains the conduit 26 substantially'vertical and stationary during the rotation of the wheel, and the downwardlyfextending portion of said body aids in preventing undue centrifugalaction of the oil ivithin the chamber or res ervoir 18, said portion of said body being suspendedin thepath of'th'e oil-andbreaking 30 the momentuniflof kthe flatter during the use of the wheel, but not v interferin gLwitha suf ficient quantity; of "Said. oil being ica'rried up-- wax-db overthe'jshaft '11 toisupplm thicon s5- q ii iv ment'of'any spec" uncut N "sweetnes ment'of bodyshow onis-the 'inventioulim ited to the-ample ft-liesriesof-aper 40 tures25; sinceithese apertuiesj naxlbei.-in-' c or reduced innumber," nor is the-invention to the formation of the COD. duit 26 frdnrtheirod of wire spirallyfcoiled, since the-,condn'it 26 is primarily a tube hav ing openings to receive the'oil carried upwardly over-the shaft-so that'the concluit may conduct such oil ma within it to said shaft.
